> This Jira is for a proposed change to the AIO "legacy" store in the Qpid C++ Broker.
> Rather than pre-allocating store files in a fixed-size ring buffer (per queue), the linear
store allocates files to queue journals on an as-needed basis, freeing them to a free-pool
when no longer needed (i.e. all stored messages have been dequeued).
> The development is ongoing in a branch called "linearstore".
